Everllence PrimeServ – Everllence’s after-sales division – has signed a contract with Navigator Gas, the liquefied-gas shipping company, for the conversion of two of its vessels to ethane-running.
Both conversions are based on the eight years of service experience gained by Navigator Gas’s ‘Navigator Aurora’ that previously underwent an identical conversion in 2018 by Everllence.
Under the terms of the project, the liquefied-gas carrier sisters, ‘Navigator Nova’ and ‘Navigator Prominence’ – both currently equipped with individual Everllence B&W 6S50ME-GI Mk8.2 engines – will be retrofitted to ME-GIE (-Gas Injection Ethane) units under IMO Tier II compliance. COSCO Shipping Heavy Industries (CSHI) will carry out the work at its Nantong yard in China.
The first conversion is scheduled to commence in March 2027 at CHI Nantong, with Everllence PrimeServ responsible for executing the scope of the engine retrofit.
Michael Petersen, Senior Vice President and Head of PrimeServ Denmark, Everllence, said: “Navigator Gas returning to us for two additional engine upgrades is a hugely positive acknowledgement of our expertise in supporting customers’ operational desire for fuel flexibility. Our proven and experienced upgrade platform offers fuel flexibility across a wide range of vessel segments, enabling the supply of cost-effective compliant fuel in an ever-changing market for shipowners.”
Petersen added: “This project represents a strategic step toward enabling alternative-fuel operation in the ethane-carrier segment. By leveraging standardised vessel designs and proven retrofit concepts, the project aims to deliver an efficient and scalable conversion solution. It also showcases the versatility of the Everllence B&W ME-GI engine that facilitates maximum fuel-flexibility and supports shipowners’ changing operational needs.”
